Abstract: Nowadays, pollution problems are a growing danger for man and his environment. Groundwater, which is considered the most potable, is the most commonly used resource in developing countries. However, this water is very vulnerable to pollution and its protection is necessary at all levels. The objective of this study was to monitor the bacteriological quality of borehole water in certain localities of the country (Mali). The bacteriological analyses were carried out under a laminar flow hood, with deep seeding. The results of the study were assessed against the criteria defined by AMANORM. Of the 30 samples of drilling water analyzed, 13.33 % were nonconforming and 86.67 % conformed for Total Coliforms (TC), 23.33 % of the samples were nonconforming and 76.67 % conformed for Thermo-Tolerant Coliforms (TTC) parameters. For Mesophilic Aerobic Germs (MAG), 46.67 % are non-compliant versus 53.33 % compliance. For Fecal Streptococcus (FSS), 96.67 % are compliant versus 3.33 % non-compliant. During our study, the drilling water samples analyzed were globally compliant at 53.33 %. The overall non-compliance rate is 46.67 %. The good quality of drinking water ensures the good health of the population, which is a condition for the sustainable development of a nation.
